Feline leukemia virus (FeLV) remains a serious concern in some countries despite advances diagnostics and vaccines. FeLV-infected cats often have reduced lifespans due to FeLV-associated diseases. The infection is transmitted through social interactions. While Northern European reported decrease FeLV among pet cats, Switzerland’s rates remain stagnant at 2.7% (2016/17: 95% CI 1.4–5.2%). Research on Swiss stray has been lacking, even though these animals could serve as reservoir. Sampling that do not receive regular veterinary care can be challenging. Collaboration with the Network for Animal Protection (NetAP) allowed prospective collection of saliva samples from 1711 during trap–neuter–return program 2019 2023. These were tested RNA using RT-qPCR measure antigenemia. Viral was detected 4.0% (95% 3.1–5.0%) samples, 7.7% 4.9–11.3%) sick 3.3% 2.4–4.4%) healthy ones. We identified three geographically independent hotspots alarmingly high (up 70%). Overall, including previous data privately owned FeLV-positive scattered throughout Switzerland 24/26 cantons. Our findings underscore welfare concerns infections lacking attention, highlighting potential risk other free-roaming those owned. This emphasizes critical significance vaccinating all outdoor access against developing programs protect infections.

Feline lymphoma is currently less commonly associated with retrovirus infections as the feline leukemia virus (FeLV) and immunodeficiency (FIV). This thought to have caused a shift in distribution of anatomical subtypes eventually led poorer treatment outcomes. The aim this study was evaluate whether change also notable Netherlands, country historically known for its low prevalence FeLV FIV, determine consequences on response. A 10-year cohort 174 cats large cell (110 treated) were included compared historical data from previously published reports Netherlands. Of 90 screened, only one tested positive three FIV. most current had an increased age (median 8.7 years) fever Siamese (6.3%) previous reports, alimentary (24.5%) nasopharyngeal (22.7%) being common subtypes. Sixty-six hundred ten (60%) went into complete remission, (CR) resulting median disease-free period (DFP) 763 days, mediastinal having longest DFP. overall survival time 274 days estimated 1-year 41.3% 2-year 34.6%, respectively. Patient characteristics malignant Netherlands changed over years, but cannot be explained by differences FeLV/FIV prevalence. Although response rate therapy did not time, some subtypes, longer DFPs observed 30 years ago.
